DETAILED DESCRIPTION OF THE PRESENT INVENTION

In some embodiments of the present invention protective tarp, the tank compartment anchors are formed of the same flexible sheet material as its central portion. Thus, both may be formed of plastic coated woven material and the anchors and baffles may be heat welded. The fill orifices are located on sides of the anchors a little distance from the top to assure that when they are filled, there is adequate airspace to accommodate thermal expansion and contraction during freeze and thaw cycles. The anchoring fill material may be any fluent material in liquid or solid form, such as water, sand, propylene glycol or a sand/propylene glycol mixture.

The present invention protective tarp may be used as a cover for any item or material e.g. to cover a log pile or for covering any other mass, such as a motorcycle, lawn furniture, sand piles, swing sets, or outdoor construction projects in progress. The tank compartment anchors may run the entire length of the edges, but this is not required; in many embodiments, there will be a plurality of tank compartment anchors along a single edge or none at all.

FIG. 1 shows a present invention protective tarp 20 which has a flat flexible sheet material 21 forming it's central portion and made of flat flexible material and has edges 23, 25, 27, and 29. In this embodiment, there are tank compartment anchors along all four edges so that the tarp may be more close ended. Edge 23 includes tank compartment anchors 31, 33, 35, 37, and 39 while opposite edge 25 includes tank compartment anchors, 41, 43, 45, 47, and 49. Ends 27 and 29 include tank compartment anchors 51 and 53. Each of the aforementioned tank compartment anchors include baffles. Thus, tank compartment anchor 41 includes baffles 42 and 44. In this embodiment the baffles run from the bottom edges of the anchors to about ¾ of the way extending towards the top edges. Additionally, they are anchored away from the fillcaps. They are not required to be angled and could be perpendicular to the bottom edges or even angled toward the fillcaps.

While present invention protective tarp of FIG. 1 has a plurality of tank compartment anchors rather than a single continuous tank compartment anchor along each side, for shorter versions single tank compartment anchors along an edge could be used. However, separate small tank compartment anchors are preferred for a number of reasons. Among these reasons:

-   -   the ability to empty one or more compartments to satisfy         anchoring requirements for specific applications;     -   the need to prevent massive fluid weight shifts when the tarp is         being moved;     -   the ability to flatten out, fold, or shorten the functional         length of the tarp;     -   containment and minimization of leaks.

FIGS. 2 a, 2 b, 2 c and 2 d show top views of different individual tank compartment anchors that form part of the present invention protective tarps (entire tarps are not shown in this figures.)

FIG. 2 a shows anchor 22 with a peripheral having a top edge 24 and a bottom edge 26. Fillcap 28 is near the top edge. Baffles 120, 122 and 124 are straight line baffles at right angles to bottom edge 26.

FIG. 2 b shows anchor 32 with a peripheral having a top edge 34 and a bottom edge 36. Fillcap 38 is near the top edge. Baffles 130, 132 and 134 are curved baffles at right angles to bottom edge 36, with top curves directed away form the fillcap 38.

FIG. 2 c shows anchor 42 with a peripheral having a top edge 44 and a bottom edge 46. Fillcap 48 is near the top edge. Baffles 140 and 142 are straight line baffles at right angles to bottom edge 46 with “T” tops, as shown.

FIG. 2 d shows anchor 52 with a peripheral having a top edge 54 and a bottom edge 56. Fillcap 58 is near the top edge. Baffles 150, 152 and 154 are straight line baffles at 75 degree angles to bottom edge 56 leaning toward the fillcap. As has now been demonstrated, many different baffle arrangements may be utilized within the scope of the present invention.

In FIG. 3, a present invention protective tarp 60 is shown. There is a singular, continuous peripheral edge 61 to central portion flexible sheet material 63, as shown. There are four attached tank compartment anchors 65,67, 69, and 71 located symmetrically on each of the four sides of the rectangle established by a flexible sheet material 63. Each of the four tank compartment anchors have a plurality of baffles angled away from the filled ports, such as baffles 73 and 75 of tank compartment anchor 69.

FIG. 4 shows a top view of a generally rectangular present invention top 80. It includes side edges 81, 83, 85, and 87. All of these edges contain a plurality of tank compartment anchors. Thus, edge 81 includes tank compartment anchors 91, 93, and 95; edge 83 contains tank compartment anchors 97, 99, and 101; edge 85 includes tank compartment anchors 103, 105, 107, and 109; edge 87 includes tank compartment anchors 111, 113, and 115. In addition, central portion 81 has a central area 82 with tank compartment anchors 117 and 119. These additional anchors will operate to minimize or eliminate wind lift and air pockets. Each of the aforesaid tank compartment anchors include baffles such as baffles 131 and 133 of anchor 113.

FIG. 5 shows a top view of another embodiment of the present invention protective tarp wherein it has been structured for production in significant lengths wherein it may be cut from a dispensing roll to create a variety of tarps of selected lengths.

In FIG. 5, present invention protective tarp 150 has side edges 163 and 167, back edge 161 and cut view front edge 165. In this embodiment, there are a plurality of central areas shown here as central areas 151, 153, 157, and 159. Along side edges 163 and 167 are a plurality of tank compartment anchors symmetrically arranged with baffles. These are typified by tank compartment anchors 175, 177, 185, and 189 along side edge 163 and tank compartment anchors 179, 181, 183, and 187 along side 167. Back edge 161 has two tank compartment anchors 171 and 173, as shown. Between each central area are multiple sets of pairs of tank compartment anchors, each of these sets of pairs being grouped equidistantly from one another so as to define the central areas shown.

Tarp 150 of FIG. 5 may come in a continuous roll form and may be cut at any point to create a tarp of any desired length. It is preferred to cut tarp 150 at locations between the pairs of tank compartment anchors that separate the various central areas. For example, cuts could be made between tank compartment anchors 191 and 193 to the left and 195 and 197 to the right. Similarly, a cut could be made between tank compartment anchors 201 and 203 on the left and 205 and 207 on the right. Alternatively, a very long tarp could be created by making a cut after tank compartment anchors 211 and 213. FIGS. 6 and 7 show tarp segments 150 a and 150 b, respectively, to illustrate preferred segment cuttings from tarp 150 of FIG. 5. With respect to FIGS. 5, 6, and 7, identical parts are identically numbered.

The present invention protective tarp may have its flat, sheet material aspects formed of any known sheet material, including synthetic and natural material, as well as combinations thereof. It may be in the form of mesh or woven material, film material or combinations thereof. It may be very wide meshed, or net-like, or very tightly woven, and it may be water permeable or water proof, but is preferably water proof. The tank compartment anchors may be formed separately from the flat sheet material and may be made of the same or different materials. Typically, however, the unconnected tank compartment anchors are made of the same materials as the flat sheet materials (with perhaps, the exception of the caps or closures), and may be integrally formed therewith. This could be accomplished in a continuous process of layered materials positioned in predetermined locations and heat-sealed to a main sheet material. The layered materials would be precut and/or preformed with a threaded or fixed cap-receiving orifice, and heat-sealed to the flat sheet material to create a tank compartment anchor.

Obviously, numerous modification and variations of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
